[Zope] Question about URL lookups

[Allen Schmidt Sr.]

Sorry if this is too generic a question but thought I would throw it out.
Interested in doing a page that does a ZSQL lookup based URL parts but 
not like a normal db lookup.
I want another way to do:
    
domain.com/LocalSearchFolder/lookup?category=27&state=va&city=Fredericksburg
More like this:
    domain.com/LocalSearchFolder/L-Fredericksburg/S-VA/C-Plumbing

And that page (ummmm...DTML preferably) would display the lookup results 
for Plumbing contractors in Fredericksburg, VA.

Any pointers to ideas??

Thanks!
